To provide a processing refrigerator capable of refrigerating directly and rapidly by cold air from an evaporator even if temperature of the whole refrigerating chamber does not reach refrigerating temperature and performing refrigerating processing at low cost in a short time.

This processing refrigerator is composed of a refrigerating vessel partitioned into a refrigerating chamber and a work chamber through an opening and closing door, the evaporator provided in the refrigerating chamber of the refrigerating vessel, and an air way guide cylinder capable of storing an object to be refrigerated and processed in the inside being the refrigerating chamber for guiding cold air from an blow-out port of the evaporator into a part in the vicinity of the opening and closing door having substantially the same size as that of an opening part of the blow-out port in the processing refrigerating device composed of a refrigerating unit provided in the refrigerating vessel for circulating refrigerant in the evaporator.
